The invention discloses a train wheel tread defect and out-of-roundness three-dimensional image pass-type detection system. The system comprises an acquisition module, a speed measurement control module, a motor moving module and a data processing module, the motor moving module is fixed on track beds on two sides of a track, and the acquisition module and the speed measurement control module aremounted on the motor moving module. The acquisition module acquires a wheel tread profile in a process of synchronously moving with a wheel, and acquires one profile at a minimum interval of 1 mm through speed measurement detection control, and an image is compressed through a preprocessing module in the acquisition process, and then is transmitted to the image processing module in time; the speedmeasurement control module measures the wheel speed and provides the wheel speed for the motor moving module; the motor moving module drives a motor to work in time according to the signal of the speed measurement control module, so that the acquisition module moves in time and keeps consistent with the wheel advancing speed; and the data processing module processes the image data compressed by the acquisition module, synthesizes the image data into a three-dimensional image of the wheel tread, and calculates out-of-roundness and tread defects.
